Kale is much cheaper than spinach. I can go to a independent green grocers even in winter and get 3-4 bunches of kale for £1 in summer more like 5
In winter you can barely get spinach in the shop, maybe £1 for 1 tiny bunch that will dissolve to nothing once cooked. In summer spinach is on a par with kale though.
Its the same deal if you try to grow it yourself. Spinach will only grow well in ideal conditions, lots of warm sunshine AND water. Kale and cabbagey things will grow all year round though and are fine in sub zero temps.
Ummm... Frozen spinach? Cheap and brilliant unless you want it in a salad.
